What we do

We set out to make the best spearguns possible for our personal use. Building on designs of innovators such as Steve Alexander and Larry Heinrich, we have developed a line of spearguns that shoot long range shots very accurately with reduced recoil. We like these spearguns so much (and so do our friends who have them) that we've decided to make them available to other divers. We like to encourage do-it-yourselfers and many of the spearfishers we know are, so we plan to add to this website all instructions and dimensions for everything we make, so you can do-it-yourself if you have more time than money. These sections are marked DIY.

If you'd like help in selecting the right gun for your type of spearfishing, check out the article Choosing The Appropriate Speargun. Note we use the Imperial system of measurement, but there is a metric conversion chart at the very end of this web page with conversions for most of the sizes listed here.

This web site is our only catalogue. We have no other brochures yet we get many requests for them, but since we are constantly adding information to this site, we don't have plans of printing brochures that would soon be out of date. After all, we are ``Internet Custom Spearguns.'' Just print this main page if you want something on paper for your reference.

Our guns and how they're made

The classic open-track, light-weight hardwood speargun works fine with light shafts of 1/4" or 9/32" diameter and one or two power bands as long as you use the single flopper tip (often called a Tahitian or Hawaiian shaft). But many divers want a longer range shot or more penetration power, so they may take a classic speargun and add more power bands, but this only harms the accuracy of these spearguns. Accuracy suffers for two reasons: 1) there is more recoil which kicks the front of the speargun upward which pushes the rear of the shaft up knocking the shaft off course and 2) the shaft actually flexes (in front of the fin tabs and behind the spear tip) from the extreme power applied when the trigger is released causing the shaft to lose power and accuracy. This flexing, often called "shaft whip," occurs with as few as three power bands. Divers try to "fix" this problem by adding side stocks, sometimes called "wings", which does help reduce recoil but only enclosed track can eliminate shaft whip. Another factor that will harm accuracy is use of a spear tip that is too heavy and bulky for a light shaft. We also make light, low-profile slip-tips (inspired by those made by Steve Alexander) to prevent this.

We decided to build spearguns that were designed properly for long range accurate shots right out of the box. These spearguns can also carry our threaded slip-tips without noticeable harm to the shot range or accuracy.

Note that it is so difficult to retrofit an open track gun with an enclosed track that the effort involved would cost more than well designed enclosed track gun. If you want to try it yourself, go ahead, but please don't ask us to do so. We would rather make a new well-designed gun from scratch than try to retrofit an enclosed track in a poorly designed underballasted, open-track speargun.

We start with hand-selected hardwood (usually Teak) with very straight grain or with many vertical laminations to prevent warping. Each stock is aged at least two months after gross cutting to allow it to stabilize, then it is precision straightened. We cut our speargun blocks very thick to provide buoyancy to compensate for the mass we add (via lead) to achieve a speargun with high inertial mass yet with balance at the handle while in the water. We precision machine an enclosed track (to prevent shaft whip). Our Deluxe spearguns are then ballasted with lead alloys until the speargun is balanced at the handle yielding a speargun that is balanced yet heavy enough to greatly reduce recoil. The recoil and shaft whip are primary factors causing inaccurate shots. Adding side-stocks can reduce recoil, but only an enclosed track can eliminate shaft whip. We believe so strongly in enclosed track that we don't intend to make any open track spearguns. Shooting an under-ballasted, open track speargun is like shooting a slingshot. Shooting a ballasted, enclosed track speargun is like shooting a 22 caliber rifle - deadly accurate with low recoil. A balanced speargun is so comfortable to use it is a delight to dive with and as far as we know, no one else is selling balanced spearguns.

One pioneering innovation is the use of a solid round rod made from a space age plastic, called Delrin, that is as slick as Teflon yet very tough. We use a solid Delrin rod which is inserted into a track we machine into the hardwood block. It is then pinned in place with stainless steel pins. We use a specially developed method to eliminate expansion stresses due to the differences in expansion rates bewteen Delrin and wood. The enclosed track is then machined into the Delrin yielding a track that is extremely slick and tough plus it won't swell in water as wood-only enclosed tracks can. This designed was pioneered by Bill Kitto. The Delrin is dense and it also contributes to speargun ballast. This makes the hottest speargun available at any price. The Delrin insert is available for a $200 surcharge (which covers the cost of the Delrin and the cost of machining the track for and pinning the Delrin), but it is well worth it - so much so, that we encourage anyone who is searching for the best speargun money can buy to get this option. A wood enclosed track can swell and pinch the shaft and may eventually wear-out becomming loose with use - particularly if used around sandy water, whereas the Delrin is extremely durable and does not suffer from either of these problems. We normally use black Delrin, but we made one speargun with white Delrin for better contrast to show more detail. We can at your request and have used other other insert material such as delrin/teflon mix, teflon, and the very expensive PEEK.

An innovation we are currently working on is the replacement of delrin with a cast in 2-part specially formulated polymer. This polymer has a greater density than delrin so it will add mass to your gun and it does not expand or contract with varying temperatures so it will impart a great addition of strength to your gun.

We feel our spearguns represent value. If you take a classic speargun and add side stocks, you may pay $1000 (or more) yet you may still have problems with shaft whip and the balance is likely to be incorrect. It is extrememly difficult to add an enclosed track to an already made open-track gun, and we won't even do it, because it is far easier to make a new gun from scratch. (Plus the speargun block needs to be perfectly straight to machine the enclosed track.)

Range and Prices

Our Basic models are price competitive with mass-market designs that lack the innovations such as enclosed track and ballasting, plus you'll find our wood stocks are much more substantial than those of our competitors. Our spearguns also come with a more durable epoxy finish (instead of Tung oil that washes out after a few dive trips) so they look nice longer. You may outgrow the classic speargun and go searching for a better speargun later (spending much more in the long run) but you will not out-grow our spearguns. Picture of gun rear view with reel.

Our Deluxe models are `fully-loaded' with Delrin insert, appropriate size of side stocks, muzzle stablizers, and full gun ballasting and balancing. These are the spearguns we use and recommend. You can get them finished or unfinished. The Unfinished Deluxe models are by far the most popular. Our Basic models are fully-rigged, wood enclosed track, finished spearguns that are still superior to other spearguns on the market. Basic models are not ballasted or balanced because they lack the side-stocks necessary for attaching ballast. We also offer a Partial Speargun Kit for do-it-yourselfers who don't have access to a machine shop, but can do other wood work.

We provide everything you need for spearfishing including spearguns, spear tips, side stocks, float lines, bungies, big game floats, speargun rigging, machining tools, and other accessories.

We continue to do research and testing to perfect the design and components used for all aspects of spearfishing. We have perfected the powerband gun and are exploring variable hi-power pneumatic guns and innovative cocking assist devices using rare earth magnets.

Summary of Speargun Features

  • We use the best components available including beefy hardwood gun blocks. Multiple ply vertically laminated stocks are available as an option for $50 more, but we may substitute them anyway at no extra charge if we can't find enough ideal solid wood.
  • Enclosed track for shaft - contributing to more accurate shots by preventing shaft whip
  • Handle is located forward from the butt as is necessary for proper balance and more stable two-handed shots. Handle location is customizable, but we won't even consider placing the handle at the rear. A rear-mounted handle yields a speargun that can not be balanced and thus is very uncomfortable and awkward while diving. Ideal handle placement depends on the length of the diver's fore arm. Proper fit is when you hold the handle in your hand with elbow bent, the butt should fit firmly against your bicep. This allows optimal range of movement and proper bracing with other hand. An inch longer or shorter is fine, but much shorter and you can not achieve proper speargun balance at the handle. Much longer and you lose ease of mobility and risk serious dental or face injury - particularly on under-ballasted spearguns.
  • Rear-located trigger mechanism - for maximal band stretch and maximum power yet not so far back as to become difficult to load. We feel the ideal placement is where the rear-most fin tab is at least 6 inches forward from the speargun butt. However, we will put the mechanism wherever you like.
  • Four (or more) power bands - for high power, long-range shots.
  • Our Deluxe spearguns are ballasted so you can shoot them one handed with a bent elbow (if you like) and you will not get hurt from recoil - even on our largest models.
  • All spearguns float with the shaft out - to reduce chance of losing speargun while fighting a fish (although you should put your left arm through the power bands while fighting the fish to avoid losing it anyway).
  • All spearguns come rigged with power bands, threaded shaft, and monofilament shooting line. Spear tips are not included. For monofilament we usually use 300 lb test line for 5/16" shafts and 500 lb test line for 3/8" shafts, but you may choose any from 300, 400, or 500 lb test. You may substitute 500 lb test coated 49 strand stainless steel shooting line for an extra $10, but note this will reduce the range and accuracy of your shot - more so on the lighter shafts than with the heavier shafts.
  • Guns typically have about 4 inches of shaft overhang (extending over the end of the speargun muzzle) without tip, so with a 5 inch tip, they will have 9 inches of shaft overhang. This is also customizable if you prefer more or less shaft overhang. It is a myth that you need lots of shaft overhang for sighting. If a speargun shoots where you aim it, you don't need it. Some find extra shaft overhang aids in aiming a speargun that shoots low (or lobs the shaft to the target). Too much overhang yields a speargun that is also difficult to balance unless you add side stocks that extend well in front of the handle. Pool tests indicate excessive shaft overhang contributes to loss of accuracy on a high powered speargun by allowing the shaft to whip.
  • All Deluxe spearguns are balanced for a specific shaft and spear tip combination. Commitment to a specific shaft and spear tip combination is critical to achieve proper speargun balance. If you plan to use different weight spear tips, we balance with the lightest then the speargun becomes slightly muzzle heavy when you use one of your heavier spear tips which is preferable to a speargun that is too light in the muzzle.
  • NEW The M6
    Kitto's newest trigger mechanism is now available. The new mechanism is extremely robust and stamped on heavy duty stamping presses from 13 guage 304 SS. The internal parts are the Kalohi design (see below) with an optional safety. The sear and 2nd member are made from heat treated 17-4 SS.
    Prices for mechanism only:
    1-5 mechanisms: $65/each
    6-10 mechanisms: $60/each
    11-19 mechanisms: $55/each
    20+ mechanisms: $50/each


  • The M5
    This ground-greaking innovation gives divers maximum performance out of their gun with virtually no 'over-cock' of the trigger.
    It works using a two-stage cocking process:

    1. You push the shaft in from the fired position until it is half-cocked. This will hold the shaft
    in place as the sear is about half-way up the notch in the shaft.

    2. Then you pull the orange loop. This pulls the intermediate lever like a crow-bar which in-turn drags the sear with it until the intermediate lever latchs on the trigger and stops in this position. This will guarentee virtually no-overcock of the sear --- thus positioning it as high as possible in the notch of the shaft.
    Testing has shown that this last "little bit" is crucial in the performance of the mechanism. 50
    thousanths of an inch difference in the notch engagement means approximately 1,000 lbs of force potential on system. I raised the top of the sear by 40 thousanths of an inch in the final configuration of the M4 and it went from consitant failure at 2,100 lbs to 2,700 lbs in the next test, wherein the carabiner holding the system in failed --- upon removal
    of the parts from the M5 under test, there was no noticable damage at 2,700 lbs.

  • The M4 - Kalohi
    The M4 is the 3 part design of Joe Kalohi. When Joe and I first discovered the solution to the trigger pull problem exhibited by 2-part mechanisms with high band load, we agreed it was a simple concept called 'nested levers'. However, our 3-part designs took separate paths from the beginning. Joe's - pictured here - has the two-spring member as the trigger. Mine - the M3 below - has the mid-part-lever with both springs. My design has the advantage of much more leverage - the mid part lever of the M3 is quite a bit longer than that of the M4. But the M4 allows for a sear operated side line release that is not available with the M3. The M4 exhibits no noticable trigger pull increase up through 1250lbs on the system. We soon will have a comparison chart with all the leading triggers and their trigger-pulls vs shaft load informating, also their fail points.
    Trigger pull info for the M4 is as follows:
    500 lbs: 1 lb 6 oz
    750 lbs: 1 lb 14 on
    1000 lbs: 3 lb 2 oz
    1250 lbs: 2 lb 14 oz
    PRICE: $132, includes line release
    Mounting fee: $120

  • Revolutionary Millenium 3 trigger mechanism *patent pending
    This new model is as far ahead of the typical 2-part design and the 2 part was ahead of the original 1-part design. Composed of 3 nested levers with unique cocking links and a remote activating lever - it specs out to give about 2 or 3 pounds of trigger pull with around 1400 lbs of force on the shaft -- mainly for tuna guns with extreme range and shaft sizes (13/32 and 7/16 shafts). The Millenium 3 mechanism, pictured below, retails at $135/unit and is available now. E-mail us for more information or to place an order.


  • Millenium 2 trigger mechanism *patent pending
    The little sister of the Millenium 3 trigger mechanism, the Millenium 2 is a two-part mechanism designed to replace and improve upon other mechanisms such as Wrife, Alexander, and even our original Millenium mechanism..

    It uses the same sear as the Millenium 3 which is stroger than the old Millenium sear. Its larger and most importantly has a much stronger pivot pin - 1/4 inch in diameter as opposed to the Millenium's 3/16. You won't find a larger pivot pin in any other competitor's mechanism. All the forces on the trigger mechanism gets concentrated on this heavy-duty sear pivot pin. The Millenium 2 also shares the Millenium 3's 'remote trigger' design.

    The Millenium 2 model retails for $85 - an associated line release and allen screw retails for $12. Our mechanism is the best you can buy (by far), but we will substitute the Alexander mechanism which is also very good, if you prefer, for the difference in our cost ($75 more). Our mechanism internals are pictured above.

    If you would like to upgrade your current mechanism, we offer free installation of our Millennium 2 mechanism (when you purchase the mechanism directly from us) into any speargun built by Internet Custom Speargun as long as you provide transportation to and from our shop. Here is where we are

  • NEW Mechanism Testing
    In this section we show how to construct an accurate tensile testing jig and the results of testing a variety of trigger mechanisms.

  • Our spearguns shoot standard shafts made by Alexander or a major manufacturer (whose name rhymes with "life" although some think it rhymes with "jiffy" and we will spell it "Wrife" so we don't use their trademarked name without permission) so replacement shafts are available at dive shops world-wide. These shafts have power band fins resembling shark fins and the front fin has a hole for attaching the shooting line. Shooting line is usually attached to the shaft fin, but you can substitute a slide ring for an extra $10.
  • We usually "open up" the last 4 inches of the enclosed track (towards the tip) to allow for easier reloading without harming shooting accuracy. If you prefer, we can leave the entire track enclosed.
  • Epoxy sealer finish with Tung oil top coat - for a durable finish that is protected from UV sunlight. An extremely durable ultra-high-gloss Polyurathane top coating finish over the Epoxy sealer with 5 year guarantee is available for $200 more.
  • Although we make standard models designed for a variety of divers and conditions, we can do custom spearguns for left handed divers or for divers of various sizes. For example, we can place the handle or trigger mechanism wherever you like, or we can make a speargun for your favorite shaft length and diameter. There is rarely an additional charge for custom work - only if it requires us to do additional work.
  • If you are visiting this website, you are probably a diver and so we hope you understand. Manufacturing a quality hardwood speargun takes quite a lot of time - approximately 36 hours just to make one unfinished Delrin speargun. We are divers who have regular full-time jobs during the week and we can only make spearguns on the weekends as a side-line. During the diving season (May through October), we spend most of our weekends diving rather than making spearguns. During the off season (November through April), we make-up inventory of our most popular speargun models. We can make you a custom speargun (to your dimensions) during the off season, but during the diving season, we are only able to sell the inventory we made during the previous off season. Send email or call to find out what we have in inventory closest to what you want. All other products we provide are available all year round. We can also do smaller jobs like mounting reels, side-stocks, muzzle stablizers, and gun balancing year round.

Partial Speargun Kits

  • Many spearos want to make a high-quality speargun, but they lack the expensive machines and tools required to do it. We take a precision straightened speagun block, and insert and pin the Delrin, machine the enclosed track into the Delrin, and install our trigger mechanism and that part is completely assembled. You do the rest or you can have us do a few more add-on services listed below under Services. A Partial Speargun Kit includes only the gun block, the Delrin rod, the stainless steel pins, and our trigger mechanism and it is all assembled. It does not include any other parts such as the handle, trigger slide, spear shaft, power bands, or any parts other than those just described, but it is a good start on making an enclosed track Delrin gun. Add $50 if you want a laminated block for your kit.
    • partial kit for guns up to 60 inches: $450
    • partial kit for guns 65" guns: $500
    • partial kit for 70 to 72" guns: $550

Slip-Tips

  • NEW Stiletto II Tip System
    The Stilletto II is an outgrowth of customer demand from the original Stilletto. The tip has now matured into an 'integrated tip system'. The system allows your basic tip to be easily and quickly changed to accomodate different shaft sizes to ensure you are prepared for all situations. A separate "restraint system" is needed for each shaft/slide ring combo and is available in either Spectra or cable.

    One complete system (tip with restraint) $103
    cable restraint $23
    Spectra restraint $25
    tip body only (with pin) $85.
  • All our slip-tips (AKA "drop-tips") use the self-centering ball and taper adaptor design developed by Steve Alexander.
  • The Spectra Stiletto Kitto's newest tip designed to be used exclusively with Spectra. $75
  • The Sleek Slayer Kitto used this tip on his last trip to New Zealand and it surpassed all expectations - he took home an 82lb tuna to prove it! $75
  • Reef Master Slip-Tip: a double-flopper hardened 17-4 stainless-steel cast tip for 5/16" & 3/8" Shafts: $75.
  • Blue Water Slip-Tip: a double-flopper cast 316 stainless-steel tip for 5/16" & 3/8" Shafts: $75.
  • Slim Slip-Tip with single flopper: our most popular slip-tip machined from 5/16" 17-4 stainless steel, then hardened.

Ballasted, Balanced Side Stocks

  • Ballasted, balanced side stocks will reduce recoil (thus increasing accuracy) and add distance to your effective shot (because less energy is lost to recoil).
  • All side stocks are made from hardwood and are balanced with lead to add ballast to and reduce recoil of a speargun that is too light.
  • All are designed for comfort while diving and loading.
  • Any of these side stocks may be added to the Alexander Magnum, Blue Water, and Tuna guns to eliminate the high recoil of these otherwise excellent spearguns. For these models we recommend at least the Small for the Magnum, the Medium for the Blue Water, and the Large for the Tuna gun. You can step-up a size for even more reduction in recoil. On some spearguns, we may have to relocate your quick release bracket to the top-side (or under-side if you prefer) of the side stock.
  • We can also make custom side stocks for almost any hardwood speargun. We recommend against using full-length "wings" because they will act like airplane wings underwater reducing manuverability of your speargun to the point of making it too difficult to track a fish. Rear-mounted side stocks do not cause any noticeable reduction in manuverability.
  • Our side-stocks are neutrally balanced so they won't change the balance characteristics of your speargun. We will mount and custom balance our side stocks to your speargun/shaft/tip combination for an extra fee of $50. This will correct any pre-existing balance problem, but some guns may require muzzle stablizers to achieve proper balance.
  • All side stocks come with attached butt pads which also help reduce the discomfort some divers feel from the butt pressing into your chest or thigh while loading by increasing the surface area of the speargun butt.
  • Our side stocks come with two stainless through-bolts that thread into stainless nuts embedded on the other side. All side stocks are finished.
  • Extra Small (approx. 12" long): $175.
  • Small (approx. 18" long): $200.
  • Medium (approx. 24" long): $250.
  • Large (approx. 30" long): $300. Top view. Side view.
  • Extra Large (approx. 36" long): $350.
  • For do-it-yourselfers, a 6 inch stainless steel machine bolt 10x24 with 3/4 inch stainless steel coupling nut (for Side Stock attachment): $6 per bolt and nut set. You need at least two to attach your home-made side stock.

Muzzles & Muzzle Stabelizers

  • The band slot has been a traditional weak point in the wooden speargun. The material removed to make the slot detracts from the strength and stability of the gun itself. The more bands you want to put on the gun - the longer the band slot becomes and the more you weaken the front of the gun. The band slot also puts the bands out of line with the shaft and end up giving the gun the 'muzzle flip' that detracts from accuracy as well. Based on the multitude of problems associated with a band slot and after many conversations with Ron Mullins and after the concept gun built by Steve Kang. We now offer a stainless steel muzzle that can handle up to 9 bands - it is very easy for the home gun builder to install and it adds strength and stability to the front of the gun instead of detracting from it. This new muzzle puts the bands directly in line with the shaft so it also does the job that front stabelizers do on a band slot d gun. Lastly you can now put the front line wrap all the way to the front of the gun instead of behind the band slot - thus giving the gun addition shooting line length. Here are some pics of this new design top view. and here it is installed on a gun

  • Stainless muzzle pair: $65

  • We also offer muzzle stabilizers which attach to the muzzle just behind the band slot. They do two things: 1) they move the bands upward so they are in-line with the shaft and 2) they are ballasted to give the muzzle more inertia. They help stabilize the speargun muzzle. We recommend adding both side stocks and the muzzle stabilizers for maximum stability and accuracy. We add both to all our personal spearguns and to all our Deluxe model spearguns.

  • Small Muzzle Stabilizers (up to 4 power bands): $125.

  • Large Muzzle Stabilizers (5 or more power bands): $150. Top view. Side view.

  • Complete package: if you get side stocks and muzzle stabilizers we will include mounting and full speargun balancing for no extra charge.

Float Lines

  • Bungie floatlines are the way to go for larger fish, but rigid vinyl float lines work fine for medium to smaller fish and they are less expensive.

Vinyl Float Lines

  • All vinyl float lines have quick attachments and swivels at both ends. They are made from clear vinyl tubing with tuna cord running through the center connecting the swivel end-plugs. The tuna cord is double crimped at each end and the ends are sealed with silicone sealant and firmly attached to the tubing. Picture of a 5/16" by 65' float line
  • 5/16" diameter float lines - approximately 300 lb test
    • 35': $38.
    • 50': $40.
    • 65': $45.
    • 75': $50.

Bungie Float Lines

  • Bungie float lines are credited to Ben Wolfe (a Fathomier) who pioneered the concept with Norprene as the bungie material. Norprene has a problem though. It is good for the first big run of the fish, but it has memory and stayes stretched out, so for the second run of large fish, it will not provide nearly as much tension on the fish.
  • Ron Mullins developed a bungie material especially formulated for tuna bungies. It is a superior elastomer material which has an extreme high modulous to fight the fish and a fast rebound to solve the second run problem observed in Norprene. This stuff just doesn't give up fighting the fish!
  • 9/16" diameter Ron Mullins inspired 3-sigma bungee float line with 2.2 times length of 1000lb urethane coated spectra 1000 cord inside connecting the end-plugs. This is the special formulation - edge of the envelope - bungee material that has proven time and time again to be capable of landing even the largest tuna and bill fish. This material has maximal rebound for run after run of even the most powerful large tuna. You can see video of this material fighting big tuna in Mullin's tuna videos. This special formulation has extreme crosslinking to give a modulus much higher than is observed in commercially available rubber. The material will exhibit approximately 200 lbs of force when stretched double its resting length - total strength with internal spectra shock cord is over 1000 lbs. It is fortunate that it is also less expensive than Norprene (which is used primarily in peristaltic pumps for medical uses).
    • 25' (stretches to 50'): $110.
    • custom length over 25': $110 + $2.40 per additional foot over 25 feet (stretches to double length)
  • 1/2" diameter Norprene bungie float line with 3 times length of 1000lb urethane coated spectra 1000 cord inside connecting the end-plugs to limit the stretch. Approximately 1200 lb test. You can use fairly large floats (or even a Kayak or small boat) with these bungies. We recommend you use the 5/32" forged anchor shackles at each end to attach to your float and to your shooting line (See Speargun Rigging below).
    • 10' (stretches to 30'): $65.
    • 13' (stretches to 40'): $75.
    • 17' (stretches to 50'): $85.
    • 20' (stretches to 60'): $95.
    • 25' (stretches to 75'): $115.

Big-Game Floats

  • Our big-game surf board floats are designed for use with a bungie for deep-diving big-game fish like tuna, wahoo, and bill fish.
  • Deluxe big-game float, made from Divinycell H60 foam core - an ultra light, ultra high-density, closed cell foam core which doesn't absorb water or crush under pressure - even under 200 feet of salt water. Core is hand-laminated with fiberglass cloth and polyester resin to provide a tough outer shell around the foam. Comes with a highly-visible yellow gelcoat top-coat - the same color used for lifeguard rescue boats. Dimensions are 16" wide by 4" thick by 36" long. The low profile and extremely light weight make it easy to tow while diving. Provides approximately 70 lbs of flotation -- more than enough for any blue water fish. Includes a red flag for increased visibility at a distance and a butt pad to reduce scratching, a front harness for float line attachment, tail harness for chaining another float line, and quick clip to aid in fighting fish: $495. each

    Free Trial Demonstrations

    • If you treat us to a day of boat diving (preferably on your own boat) to an area with clear blue ocean water and game fish (such as the Channel Islands off the coast of California), we will bring a few of our speargun models (of your choice) for you to try for yourself. You may use them all day if you like so you can evaluate the quality of our spearguns. Compare them side-by-side to any other speargun made in the world. We are confident that once you try one of our spearguns you will know they are by far the best available. We will provide our own transportation (even airfare if necessary) to your boat. Southern California diving is easiest for us, but we may be willing to travel elsewhere if you can provide a place for us to stay for a few days. You are under no obligation to buy a speargun and you can do the free trial even if you have no interest in getting one. We will be happy just to dive.
    All prices are in US dollars and are subject to change without notice.
    Federal law requires collection of a 10% excise tax on spearguns and parts.
    8.75% sales tax must be added for orders from California residents.
    Ask about cash discounts.
    Packing and UPS shipping are available at cost.
